摘要：This talk presents recent advances in our group for topology optimization based on phase-field methods. First, a phase-field model for coupled thermal-fluid design is introduced, including well-posedness, existence of optimal designs, adjoint-based sensitivity analysis, finite element discretization, and efficient gradient-flow algorithms. Second, alternating phase-field Fourier neural networks are developed as a mesh-free framework that separately represents state, adjoint, and topology variables for compliance minimization, eigenvalue maximization, and design of fluid flows. Numerical results will be reported.
